There’s a lot of info there, including tons of plot stuff, so don’t look if you want to stay pure.

The sequel, again set in Rapture, casts you as a plasmid-touting Big Daddy up against a Big Sister and splicers that are “even less human” that before, according to that piece.

Of the Big Sister:

Given the raw power and range of abilities the big daddy you’ll play, the team felt the need to create a formidable predator. We saw hints of her handywork in the debris throughout the level, which included numerous battered big daddy corpses. But it wasn’t until she popped into sight that we got a sense for how dangerous she is. The big sister is a lithe being that’s unsettlingly thin, but has a fat needle arm, and a cage on her back to hold little sisters. She’s fast, maneuverable, and has special abilities of her own. In her brutal attack in the demo, she had what appeared to be a telekinesis plasmid–which she used with deadly accuracy.

A general embargo’s about to lift, so keep watching over the weekend for similar deals from other sites.
